0A heavy nucleus splits into lighter nuclei which are more stable the original heavy nucleus. When a heavy nucleus like uranium is bombarded by slow moving neutrons, it breaks into two parts releasing large amount of energy. The typical fission reaction of Uranium.
\( { }_{92} \mathrm{U}^{235}+{ }_{0} n^{1} \rightarrow{ }_{56} \mathrm{Ba}^{141}+{ }_{36} \mathrm{Kr}^{92}+3_{0} n^{1}+200 \mathrm{MeV} \)
The fission \( { }_{92} \mathrm{U}^{235} \) approximately released 200 \( \mathrm{MeV} \) of energy.
Einstein's mass-energy conversion relation \( \mathrm{E}=m c^{2} \) is illustrated by
(A) nuclear fission
(B) \( \beta \)-decay
(C) rocket propulsion
(D) steam engine
